POCKET-KNIFE.

SPECIFICATION forming part of Letters Patent N0. 234,731, dated November 23, 1880,

Application filed October 6, 1880.

To all whom it may concern:

Be it known that I, NELsoN B. SLAYTON, a citizen of the United States, residing at Alfred Centre, in the county of Allegany and State of New York, have invented certain Improvements in Cutlery, of which the following is a specification.

My invention relates to an instrument for pocket or table use, and is especially adapted to fruit-knives and nut-picks. In the drawings I have shown a fruit-knife and nutpick combined in one handle; but either may be employed independent of the other. The first seven figures illustrate a single blade hinged or pivoted to the handle at its middle and having a nut-pick formed on one end and a fruitknife on the other. This instrument is intended for table use, and one end of the blade is, of necessity, always exposed. In the remaining figures is illustrated the pocketinstrument having the nut-pick and knife made separate and hinged on opposite sides of the handle, so that both may be folded in at the same time.

The leading feature of the invention consists in forming the pocket to receive the blade when closed in the side of the handle, and beveling off the marginal rim that is raised around the recess toward the point where the blade is pivoted or hinged, so as to permit the blade to spring into its recess when closed, all as will be more fully hereinafter set forth.

In the first seven figures of the drawings, Figure 1 is a side view of the table-instrument, showing the blade partly open. Fig. 2 is a view showing the nut-pick end of the blade closed and the other or fruit-knife end open for use. Fig. 3 shows the opposite end of the blade open. Fig. 4 is a view of the back of the instrument; and Figs. 5, 6, and 7 are respectively cross-sections taken in the planes of the lines a as, 3 y, and z z in the first three figures.

Let A represent a fruit-knife or knife-blade and B a nut-pick. In the present case these are formed on opposite ends of one plate or piece, which I call the blade, the pivot a, by which it is attached to the handle, being nearly in the middle, as shown.

0 is the handle, which has a shallow recess or pocket, b, in its side to receive the ends of the blade. This recess is formed by raising (ModoL) around it a rim, 0, which rises as high as the thickness of the blade at the butt d of the handle, but is beveled toward the end where the blade is pivoted until it runs out entirely, or nearly so, at c e. The face of the handle, to which the blade is pivoted, is in the same plane or on the same level with the bottom of the recess I).

At f f recesses or. nicks are formed in the handle to receive or engage pins or project-ions g g on the blade and prevent the latter from movingtoofarineitherdirection. These serve as braces to sustain the pressure when the instrument is beingused.

The pick B, when the knife A is opened, rides up the beveled rim or ledge c and springs into the recess 1), while a pin or stop, 9, on it engages one of the notches f in the handle. When the instrument is folded into the recess 1) it will not interfere with the grasping of the handle, but on the contrary serve to fill or partly fill the said recess, as best illustrated in Fig. 3.

A slight pressure on the open end of the blade will serve to lift the opposite end out of the recess, when the position of the ends may be readily reversed, as shown.

The pocket-instrument shown in the next five figures does not differ materially from that just described, the main point of variance being the independence of the nut-pick from the fruit-knife blade and their arrangement on opposite sides of handle.

Fig. 8 is a side view, showing the pick and blade partly open. Fig. 9 shows both closed. Fig. 10 shows the knife-blade open. Fig. 11 shows the opposite side of the handle with the pick open; and Fig. 12 shows a cross-section of the handle, taken in the plane of the line 2 z in Fig. 8.

In this construction, as each blade or part A and B has an independent recess, 1), it is only necessary to bevel the raised rim on one side, as the pick and knife both open in the same direction. The stop 1 is, in this case, formed on the butt of the blade, as shown, and engages a recess,f, in the handle, similar to that shown in Fig. 1.

I prefer to form the extremity of the handle which is clasped between the but-ts of the blades or parts A and B to correspond with said butts, as indicated at h in Fig. 8, so that when both blades are closed the said butts and the part h of the handle may present a uniform finish, and not be liable to cut the pocket.

I am aware that it is common to hinge blades or parts at their middles and form tools or instruments on their ends, and to arrange these to fold between the two checks of the handle; but in my invention, which contemplates the employment of blades or instruments hinged either at their middles or at their ends, the handle is solid and the instrument rests, when closed, in a recess or pocket in the flat side of the handle. This is the distinctive feature of my present invention.

Although I have described the parts A and B as a fruit-knife and nut-pick, respectively, it is obvious that the same method of mounting and construction might be employed for surgical or other instruments for various pur poses.

Having thus described my invention, I claim- 1. An instrument composed of a handle and a folding blade or part hinged thereto, the said handle having an open recess in its side,

with a low rim around it, to receive the blade when shut, the said blade being sprung into said recess over said rim, substantially as set forth.

2. An instrument composed of a blade and handle, as shown, the said handle having an open recess in its side, with a low rim around it, to receive the blade when shut, the said rim being beveled down toward the point where the blade is hinged, so as to permit the blade to ride up over it more readily when being closed, substantially as set forth.

3. The combination of a handle, 0, having an open or shallow recess in one or both sides, partially surrounded by a low rim, 0 c, and

nicks or recessesff, with a blade or blades hinged to the end of the handle, as shown, and provided with stays or pins 9 g to engage the nicksff, all substantially as and for the purposes set forth;

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
